(Cl. 20G-41) 3 Claims.

This invention relates to tobacco pouches and has particular referenceto pouches which are made of relatively cheap materials such as wax orrubber-impregnated paper and are thrown away after use. Such pouches, asnow made, are far from satisfactory since they tear easily at the uppercorners of the tobacco-receiving pocket andbecome unfit for use beforethey are emptied of their contents.

The object ofthe present invention is to provide a wax orrubber-impregnated paper pouch in which the upper edge of the frontwalland the upper corner portions of the tobacco-receiving pocket` arestrengthened so that they constitute the strongest portions of the.pouch and will withstand, without tearing, the lstrains to which theyare subjected in the ordinary usage of the pouch.

According to this invention the upperA edge of the front wall of thetobacco-receiving pocket is reinforced throughout its entire length by areinforcing element having extended end portions which are bent inwardlyand secured to the rear pocket-forming wall o'f the Apouch to reinforceand strengthen the upper corner portions of the pocket. This reinforcingelement may be formed as an integral part of the blank from which thepouch ismade or it may consist of a separate reinforcing strip ofCellophane vor other suitable material having a higher tear resistancethan the wax or rubber-impregnated blank from which the pouch is formed.

Several examples of the invention are illustrated by the accompanyingdrawings, in which- Fig. 1 is a front view of a tobacco pouch in whichthe pocket-reinforcing element constitutes an integral part of the blankfrom which the pouch is formed.

Fig. 10 is a front view of pouch inwhich a separately formedpocket-reinforcing element is folded over the upper edge of the frontwall of the tobacco-receiving pocket andls provided with extendedcorner-reinforcing end portions secured to the rearwall of t-he pocket.

Fig. 11 is a sectional view'taken along the line i2-I2 of Fig. 10.

'I'he pouch shown in Figs. 1 yto 4 inclusive comprises atobacco-receiving pocket 6 and a closure iap 6. The pocket B is formedby front and rear walls 1 and l integrally joined at their lower edgesand -adhesively secured together at their side edges. The ilap '6 isformed .as an in tegral continuation of the upper edge of the rearpocket-forming wall I and is adapted to be folded around the pocketportion of the pouch in the usual manner. 'I'lie front pocket-formingwall 1 is folded to provide a two-ply upper edge consisting of the outerand inner plies 9 and il. These plies are formed so that they conjointlypresent extended two-ply end portions Ii which,

asshown in Fig. 2, are folded around the sides of the pocket 5 andadhesively secured to the outer surface of the rear pocket-,forming wail8 to strengthen vthe upper corner portions of the pocket. While theextended comer-reinforcing end portions Ii of the two-ply upper -edgeportion of the pocket-forming wall 1 are preferably secured to the outersurface of therear wall l, it will be understood that, if desired, saidcornerreiniorcing end portions ii may be bent inwardly and secured tothe front surface df the rear pocket-forming wall I. The frontpocket-forming lwall 1 is provided with inturned side edges 1a which areadhesively secured to the rea-r surface of said wall and to the frontsurfaces of similar inturned side edges 8a of the rear pocket-formingwall l. The ap 6 is formed with intumed side edges 6a which areadhesively secured to the body of the ap and form integral continuationsof the inturned side edges of the rear` -aiurther form of also creasedvertically as indicated at C and D, the marginal portions of the blanklying outside these creases being folded inwardly to provide theaforesaid inturned side edges of the pocketforming walls l and 8 and theilap 6. Near its lower end the blank is provided with slits I4 extendingoutwardly from the vertical creases C and D. The portion of the blanklying below these slits is bisected by a horizontal crease E along whichit; is folded to provide the aforesaid two-ply upper edge portion andcorner-reinforcing extensions of the front pocket-forming wall 1.

The pouch shown in Figures 6 to 9 inclusive is strengthened by aseparately formed reinforcing strip 25 which extends across theoutersurface of the front pocket-forming wall 'l at or adjacent the upperedge of said-wall and is provided with extended end portions 26 whichare bent around the sides of the pocket and secured to the outer surfaceof the rear wall 8. This separately formed reinforcing strip 25 ispreferably made of cellophane but may be made of other materials. Theextended ends of the separately formed reinforcing strip 25 may, ifdesired, be turned inwardly between the walls 1 and 8 and secured to thefront surface of the'wall 1.

The pouch shown in Figs. l and 11 is also provided' with a separatelyformed reinforcing strip 28 but, in this case, the reinforcing strip isrelatively wide and is folded about the upper edge of the pocket-formingwalls 'l and 8 to provide inner and outer reinforcing plies 29 and 30which are integrally united at their upper edges provided with inturnedside edges which are adand are adhesively secured to the front and rearsurfaces of the interposed pocket-forming wall 1. The folded typereinforcing strip shown in Figs. 10 and 11 is provided with two-ply endportions 32 which are turned inwardly and secured to the outer surfaceof the pocket-forming wall 1. It will be understood, however, that theextended end portions 32 of the reinforcing strip shown in Figs. 10 and11 may also be turned inwardly and secured to the inner or front side ofthe rear pocket-forming wall 8.

Having thus described what I now consider to be the preferredembodiments of my invention it will be understood that I reserve theright to all modifications that fall within the scope and hesivelysecured together in face to face relation, said front pocket-formingwall being provided with a. reinforced upper edge having extended endIportions which are bent inwardly to overlie and to be adhesively securedto the outer or rear surface of the rear pocket-forming wall 2. A pouchas set forth in claim 1 in Iwhich the material of the pouch is foldedupon itself at the upper edge of the front pocket-forming wall toprovide the aforesaid reinforced upper edge.

3. A pouch as set forth in claim 1 in which a separately formedreinforcing element is folded over the upper edge of said frontpocket-forming wall to provide the aforesaid reinforced upper edge.
